SPECIFICATION forming part of Letters Patent No. 468,677', dated February 9, 1892. Application filed March 12, 1891. Serial No. 384,781. (No model.)

To all whom t may concern,.-

Beit known that we, JOHN H. MAXHEIMER, a resident of New York, in the county and State of New York, and GEORGE C. BEEEs- FORD, a resident of Sound Beach, in the county of Fairfield and State of Connecticut, both citizens of vthe United States, have invented a new and useful Necklace-Clasp, of Awhich the following is a specification.

Our invention relates to a necklace-clasp in which the catch of the clasp when inserted in the box of the clasp is locked Within the box of the clasp by vmeans of a clip.

The object of our invention is to provide al necklace-clasp which will be a means of securely fastening a valuable necklace about the neck of a wearer. While the clasp is especially adapted to be used upon necklaces, it is readily available for bracelets or other forms of jewelry. We attain this object by the device illustrated in the accompanying drawings, in which Figure l is a View of a longitudinal section of the necklace-clasp on the line l l of Fig. 2, showing the box A, spring-catch C, and clip B. Fig. 2 is a view of a longitudinal section of the necklace-clasp on the line 2 2 of Fig. l, showing the box A, spring-catch C, and clip B. Fig. 3 is a view of a transverse section of the necklace-clasp upon the line 3 3 of Fig. 2,

showing the box A, spring-catch C, and clip B. Fig. 4 is a view of a longitudinal section of the necklace-clasp, showing the box A, spring-catch C, and clip B, with projecting end and pin b, spring 12', and partition a.

Similarletters refer to similar parts throughout.

In the drawings the necklace-clasp is shown in enlarged form. Our necklace-clasp, which is constructed of gold or other suitable material, is provided with a box A. I The box A (shown in the drawings) is four-sided; but it may be constructed in cylindrical, oval, or other suitable shape. A spring-catch C fits into one end of the box A, a projection c upon the spring-catch engaging in a slot D in the box A and holding the spring-catch in place. Pivoted in the sides of the box A, at b and Working in an opening in the box, is a clip B, having a clutch-headb. The clutchlhead h is adapted when the clip is pressed inward to pass through the spring-catch C, thereby preventing the spring-catch C from being drawn outward, Figs. l, 2, land 3.

To obviate any tendency of the clutch-head b of the clip B to Work out of position when locking the spring-catch C, a projecting end, with pin h, is constructed upon the clip B, the pin b being inserted into a spring b" in contatct with a partition a in the box A, Fig. 4.

The operation ot' our necklace-clasp is as follows: One end of the necklace or bracelet is attached tothe spring-catch C by a lug c or other suitable fastening, and the other end of the necklace or bracelet is attached to the box A by a similar lug or fastening a. The spring-catch C is compressed and inserted into the box A. The clip B, having been drawn outward to allow of the insertion of the sprin gcatch C into the box A, is again pressed 1nward and through the spring-catch, the clutchhead h locking the spring-catch in the box A, Figs. 1,2, and 3. When the necklace-clasp is constructed with a clip B, having a projecting end with pin b, in connection with spring h and partition a', the pressure of the spring b" from the direction of the front of the box A upon the projecting end and pin h holds the clip B in locking position through the spring-catch C. If the clip B be drawn outward, the spring b is compressed and causes the clip when the outdrawing force is relieved to spring back in locking position through the spring-catch C, Fig-l. This construction is especially well adapted to prevent the outdrawing of the clip B should it become entangled with laces or other fine fabrics.

Having fully described ourinvention, what we claim, and desire to protect by Letters Patent, is-

' 1. The combination, in a necklace-clasp, of a box, a spring-catch adapted to be inserted in said box, and a clip to lock said springcatch in said box, the clip when in locking position passing through the spring-catch, substantially as set forth.
